Question

How much production of halogenated pollutant annually?

Answer 1

Halogenated Organic Compounds

Halogenated compounds constitute one of the largest groups of environmental pollutants. Contamination of marine and freshwater sediments by anthropogenic halogenated organic compounds, such as solvents (tetrachloro ethylene[PCE], trichloro ethylene [TCE], dichloro ethylene [DCE], chloroethylene [CE], trichloro methane[TCM], and dichloro methane [DCM]), pesticides (DDT, TCE), polychloro dibenzofurans (PCDFs), and dioxins, is a matter of increasing concern. The majority of these compounds are chlorinated, but brominated and fluorinated aromatic compounds are also in use. Microbial processes based on the metabolic activities of anaerobic bacteria are very effective in the degradation of these compounds. They are known to play important roles in nature by preparing many of these compounds for subsequent biodegradation, predominantly by the aerobic means. A critical step in degradation of organohalides is the cleavage of the carbon-halogen bond (Leisinger
